Abstract: Theoretical and numerical investigations are carried out into the inverse pinning effect of platelet particles on the grain boundary migration. The theoretical expression for the driving force of the inverse pinning proposed in an early work is first revisited and modified to remove the limitation in the volume fraction of the particles. In addition, it is shown that there exists the maximum velocity of the grain boundary due to the inverse pinning. The validity of the present considerations is demonstrated by phase-field simulations for the grain growth. (C) 2013 Elsevier B. V. All rights reserved.
